ICE-VELOCIPEDE.

SPECIFICATION forming part of Letters Patent No. 407,876, dated July 30, 1889.

Application filed February 16, 1888. Serial No. 264,192- (No model.)

To all whom, it may concern:

Be it known that I, J osnrn E. ROBINSON, a citizen of the United States, residing at Oil City, in the county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in Ice-Velocipedes; and I do hereby declare the following to be a full,

,clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same. This invention relates to ice-velocipedes; and it consists in certain improvements in the same, as will be hereinafter described, and pointed out in the claims.

The invention is illustrated in the accompanying drawings as follows:

Figure 1 is a side elevation of the device complete. Fig. 2 is a front elevation of the same. Fig. 3 is a vertical section on the line 00 x in Fig. 2. Fig. 4 shows a detail of construction.

The construction of my device is as follows: A A are the runners, which are connected together and supported by cross-beams A A", and these cross-beams are bound together by a plate A. On the lower side of the plate A there are hangers a a, in which is pivoted in a position parallel to the runners a rock-shaft J, having arms J, carrying guard-runners J either one of which can be thrown into action by tilting the shaft J. (The means for tilting the shaft J willbe described in proper connection further on.) On the front of the runners A are wheels A, which are so placed that they do not touch the ice when the runners are flat upon it. The object of these wheels is to enable the machine to be run on the ground by tipping it forward, so as to make it bear on these wheels, and also to prevent what are called headers when running the machine on ice.

On the plate A there rests another plate B and there are rollers b interposed, so that the two plates can turn easily upon each other. These two plates act the same as the fifthwheel of a carriage. On the plate B is an upright frame-work or tripod B B B. On this frame-work or tripod is a rod 1, which extends above it and holds the guide-arms G. At its lower end the rod I connects by a universal joint I" with a square head I in the plate A hence by turning the arms G the plate A? and and when the runners are turned so as to make a curve the frame 13 B B will incline toward the center of the curve. 011 the framepiece B there is a pin 1), carrying a roller b and on the shaft J there is a Y-shaped piece j, which embraces in its fork the pin 1). It will be seen that when the plates A and B turn upon each other the pin 6 will move the Y-piece and tilt the shaft J, and this will throw one or the other of the guard-runners J 2 into contact with the ice, as required. The guard-runner thus brought into action is always the one farthest from the center of the curve in which the machine is running, and if this curve is sharp and made at high speed the guard-runner will prevent the machine from sliding sidewise.

The propelling apparatus consists of the treadle-cranks FF, the crank-shaft F, the sprocket-wheel F on said shaft, the propeller wheel D, sprocketwheel D on the hub of said propeller-wheel, and the sprocket-chain E. The propeller-wheel is hung in a frame 0 C 0 which is pivoted at c to a clip O on each of the uprights B.

The wheel .D is a piked wheel, and the part O of the frame is a guard to prevent the pikes from catching the clothing of the rider. The object in having the frame O O C pivoted is to enable the driving-wheel to be lifted up off of the ice at will, and also to follow the inequalities of the surface of the ice. The means for lifting the driving-wheel is a hand-grip lever H on the guide-bar G, a slide N, and a rod 11 which takes hold of the frame at the axis of the wheel D. Of course this rod H may take hold of the frame at almost any point and effect the result.

The boxes O carrying the crank-shaft F, are secured to clips 0 pivotally. The pivotbolt 0', however, should not be loose, the object of the pivot or joint being to easily effect alignment of the boxes when setting the machine up.

The standards B B are made parallel to each other for a short distance at the point where the clip 0 is secured, so as to allow said clip to be vertically adjusted on the standards, and thereby adjust the cranks to suit different-sized riders.

K is the saddle. K is a spring supporting the saddle, and K is a brace supporting the sprlng.

What I claim as new is 1. In an ice-velocipede, the combination of a horizontal frame having runners, an upright frame, so as to turn horizontally thereon, pivoted to said horizontal frame, a guiding apparatus pivoted in said upright frame and operating upon said horizontal frame, a propelling-Wheel journaled in aframe pivoted to the said upright frame, a lifting device for' lifting said driving-wheel frame, and a treadle device for imparting motion to said drivingwheel.

2. In an ice-velocipede, the combination of a horizontal frame having runners and an inclined disk or plate A, an upright frame having at its base an inclined plate or disk B which sets upon and moves pivotally on the plate A a universally-jointed stem I, eX- tending from the plate A to the top of said upright frame, and arms for Working said stem I pivotally in said upright frame and turning the said horizontal frame pivotally upon the said upright frame.

3. In an ice-velocipede, the combination of a horizontal frame having runners, an upright frame carrying the propelling apparatus, which is pivoted to said horizontal frame so as to turn horizontally thereon, and a steering apparatus for turning said horizontal frame, Which is pivoted longitudinally in said upright frame.

4. In an ice-velocipede, the combination of a horizontal frame having runners, Wheels at the points of said runners, an upright frame pivoted to said horizontal frame, and a propelling apparatus mounted on said upright frame.

5. In an ice-velocipede, the combination of a horizontal frame having runners, a tilting frame having guard-runners pivoted to said horizontal frame between said runners, an upright frame pivoted to said horizontal frame,

is pivoted on said upright frame, and a lift-' ing device for lifting said propeller-Wheel.

7. In an ice-velocipede,the combination of a horizontal runner-frame, an upright frame supporting the riders seat, Which is pivoted to the said horizontal frame so as to turn horizontally thereon, a pedal apparatus supported by said upright frame, a driving-Wheel supported in a frame which is pivoted to said upright frame, gearing for driving said drive- Wheel from said pedal apparatus, and a lifting device for lifting said driving-Wheel.

In testimony whereof Iaffix my signature in presence of two Witnesses.
